American Samoa /səˈmoʊə/ (audio speaker iconlisten) (locally /ˈsɑːmoʊə/; Samoan: Amerika Sāmoa, [aˈmɛɾika ˈsaːmʊa]; also Amelika Sāmoa or Sāmoa Amelika) is a territory of the United States. It is part of the Samoan Islands in the southern Pacific Ocean.

In 1899, Germany and the U.S. divided the Samoan group of islands. The U.S. got the smaller group of islands on the east side. These islands had a good harbor near the capital city, Pago Pago. The western islands were run by Germany and then by New Zealand and are now the independent country Samoa.

Officially, American Samoa is an "unorganized" territory. This means that the U.S. Congress has not passed an Organic Act. But the people who live in American Samoa rule themselves. Their constitution became effective on July 1, 1967.

The capital of American Samoa is Pago Pago, but the seat of government is Fagatogo.
